안녕하세요 난이 이것 좀 봐 현재의 문제, 안드로이드
알고, 나는 내가 잘못 찾을 수 없습니다
여기은 내 XML :
<?xml version="1.0" encoding="UTF-8"?>
<menu>
<item>
<name>Margherita</name>
<description>Single cheese topping</description>
</item>
<item>
<name>Double Cheese Margherita</name>
<description>
<![CDATA[
<ul>
<li>item 1</li>
<li>item 2</li>
<li>item 3</li>
</ul>
<span>Loaded with Extra Cheese</span><br />
]]>
</description>
</item>
</menu>
설명을 HTML 내용이 포함 된 String으로 가져와야합니다.
Adapter.java : 아니라 첫 번째 작품은 여기
내 코드는 ...<![CDATA[가 비어으로
<![CDATA[ 그러나 두 번째
없이 설명을 얻을 수 있습니다 XMLParser parser = new XMLParser();
String xml = null;
try {
xml = parser.readTextFile(context.getAssets().open(FILENAME));
} catch (IOException e1) {
e1.printStackTrace();
}
// getting DOM element
Document doc = parser.getDomElement(xml);
// Extract items from DOM
NodeList nl = doc.getElementsByTagName(KEY_ITEM);
for (int i = 0; i < nl.getLength(); i++) {
Element e = (Element) nl.item(i);
Medoc m = new Medoc();
// fill Medoc informations
m.setTitle(parser.getValue(e, KEY_NAME));
m.setDescription(parser.getValue(e, KEY_DESC));
// save in memory
data.add(m);
}
